However, his son Buyeo Pung escaped to Japan, and together with Yamato general Abe no Hirafu unsuccessfully attempted to restore the kingdom.

[2] Kudara-no-Konishiki Kyōfuku was the great-grandson of Zenkō and in his role as nominal governor of Mutsu Province found a large deposit of gold which was donated to the Court for use in the completion of the Daibutsu at Tōdai-ji in Nara.

The temple was destroyed by fire around the 11th and 12th centuries, roughly around the time the Kudara-no-Konishiki clan vanishes from the political landscape and was never rebuilt.

The site was excavated first in 1932, and based on the foundation stones uncovered, it was determined that the temple has a "Yakushi-ji"-style layout, consisting of a South Gate, Middle Gate, pair of pagodas side-by-side, a Main Hall and a Lecture Hall contained within an area approximately 200 meters on each side.

A second excavation was made in 1965, which discovered at a cloister connected the Main Hall to the Middle Gate, making the layout closer to that of the Kanon-ji temple ruins in Silla rather than Yakushi-ji.
